Custom Agents

The text discusses the introduction of new abstractions for creating custom agents in Python and TypeScript modules. A BaseSingleActionAgent is presented as the highest level abstraction for an agent that can be used in their current AgentExecutor, with a more practical LLMSingleActionAgent also introduced. This LLMSingleActionAgent is highly modular and customizable, consisting of four parts: PromptTemplate, LLM, stop sequence, and OutputParser. The text also outlines future directions for the development of agents, including SingleActionAgents using embeddings or a ConstitutionalChain, as well as Multi-action agents and Plan-execute agents.
